English Oracle text
Until end of turn, target nonland permanent loses all abilities and becomes your choice of a blue Frog creature with base power and toughness 1/1 or a blue Octopus creature with base power and toughness 4/4.
「お願いだ。カニになってくれ！」土地でないパーマネント１つを対象とする。ターン終了時まで、それはすべての能力を失い、基本のパワーとタフネスが１/１の青のカエル・クリーチャーか基本のパワーとタフネスが４/４の青のタコ・クリーチャーのうち、あなたが選んだ一方になる。
Lesson is a spell subtype found on some instant and sorcery cards in the Strixhaven set. The Lesson subtype has no special rules associated with it.
Although you may want to include Lessons in your sideboard if you’re playing with cards that instruct you to learn, Lesson cards can be included in your main deck like other instant or sorcery cards.
You choose Frog or Octopus as Mercurial Transformation resolves, not when you cast it.
Legality follows the dated Scryfall catalog snapshot.
